Subject: Intermittent problem: can't write to properties of $this
From: tsteiner@nerdclub.net (Tim Steiner)

Greetings,

I'm currently trying to troubleshoot an intermittent problem on one of 
our servers.  After some time of running just fine (usually a couple of 
hours),  scripts will start throwing the warning "Attempt to assign 
property of non-object" when writing to a property of the $this object. 
  Once it starts, it seems to keep happening every few requests (with 
other requests running as expected).  The poster at 
http://www.zfforums.com/zend-framework-components-13/core-infrastructure-19/warning-attempt-assign-property-non-object-zend_config-5469.html 
seems to be having the same issue.

I've traced the warning output to line 576 of Zend/zend_execute.c, which 
means that something is happening to the write_property of the object. 
At this point, I don't have enough knowledge of the internals to 
continue tracking this bug down.  Any help would be appreciated.

Thanks!
